Herald of the Storm

Im planning to make a necron army for the medusa V camp, and i was wondering if they would release a Herald of the Storm (necron lord character) model... or at least publish rules for him in WD... as from the Medusa V bit in the recent aussie WD it explained something about his abilitiy to control weather. this seems pretty dam cool... and would be awsome to have him in your army? what are your thoughts?
